' Objective.

This invention relates vto a machine forl molding and pressing' bricks, the press being worked by a pair of segment gears or levers. engaging in a vertical standard and operated by a series of revolving radial arms, whereby said standard is raised and lowered for pressing the b1icks,.as hereinafter more fully described.

Descriptive.

In fig. 1, Lrepresents a case or body of the machine into which the clay is thrown to be reduced to la proper consistency for molding, and which is done bya system of revolving radial arms, as ordinarily practiced. l

At the lower front end of the case is the press-box B, iig. 5, into which the clay is received from the case and forced into the mold C, immediately under said box, by means of the follower t-ted therein D, fig. 2, andv attached to the lower end of the standard E, whereby it is operated by the segmental gear or levers F Gr,- g. 1, as hereinafter. shown.

H is a shaft, standing vertically in the center of the case, to the upper end of which is secured a wheel, I, to 'which motion is given by a pinion, J, secured to the shaft K.

To said wheel I are pivoted six radial arms LM, all of which may be turned up to a vertical position, as shown in gs. 1 and 5. y

It will be observed that four of said arms L are arranged at right angles to each other, as shown in -fig. 2, whereas the two arms M, which are shown as being turned vup,`and represented as extended by the dotted lines c, in Eg. 2, together with the arm L', are arranged equidistant in the wheel, forming trinity of arms instead of a quartering, as in the above instance, the purpose of which will presently be show n.

- To the lower end of the shaft H, immediately nnder the bottom of the oase,'is'secured a'ivheelN,nfig.

3, in which is arranged a duplication of the pivoted arms just described, and with which they relatively co-Opelate in their numerical number, and which arealso indicated by corresponding letters.y

Below said wheel is a shaft, 0, having its bearings in the sides of the base ofthe case.

To said shaft is secured an arm, P,.iig. 2, to the` Operative.

The operation of this machine is as follows, viz: The clay, on being properly prepared, isthen forced from the case into the press-box referred to, under which is inserted amold S'. Through the-openingTin the side of the case, a second mold', U, is' inserted be tween that immediately under the press-'box andthe slide Q. This being done, the clay is forced from the box into the mold underneath by the follower D, which is driven downward from the position seen in iig. 1 to that shown in fig. 4, thereby forcing the clay from the boxv through the bottomA into the mold bes low.

The arm L, on leaving the lever F, immediately engages th'e lever G, thereby elevating the follower again to' the position seen in g. 1, Whichjs again forced down by the next arm L, in the Iorder of their arrangement, which, in this instance,'is four times during one revolution of the wheel I, thereforeA filling four molds in succession at each rotation of the wheel and arms.

During the same time the filled molds are discharged from under the press-box by the slide Q referred to, which is' operated as above said by the arm P, whichis thrown forward by the' radialarms`L dur- .ing the revolution of the wheel N.

The arrangement of th'e radial arms of the wheel N is such as'to conform tothat of the radial arms of the wheel I in number, position, and their revolution is so. timed in relation to the movement of the follower vthat the slide is pushed forward at the instant that said follower begins to ascend, thereb'j,T pressing against the side of the' empty-mold-V, f1g.,v

-forcing it outward against the filled mold S, which -will bedriven from under the press onto the table W, as indicated by the dotted lineskb, iig. 5, and,`asa consequence, bringing the empty mold under the press to' be lled by the now descending follower, during which descent is inserted another empty mold behind thatunder the press, which, in like-manner,wi1lbe forced under the press by the slide, and, in turn, pushing forward the nowfilled mold onto the table, and so rating the arms one, two, and three, fig. 2,*and eX-' tending the arms M, as indicated by the dotted lines c, also, the arms for discharging the molds mustv be `arranged correspondingly. This change will lessen the capacity of the machine one-fourth, giving three filled molds at each revolution instead of four.

The capacityv of the machine may bereduced to one-half by erecting all the arms but two; said two should be those left in line with one diameter of the wheel, so as to equalize the timely movements of the press.

The degree of pressure expended upon the molds may be graduated by the har A', g. 1, under which the ond of the radial arms pass as they rotate, and by which they are prevented from slipping from their engagement with the lever F until the arrival of the arm to the shoulder B of the bar. The arm 'then will slip over the shoulder and slide oi over the end of the lever, thereby relieving the mold from further pressure.

It will be obvious that the longer the radial arm vis continued in contact with the lever the greater will be the downward movement of the follower, hence', a greater pressure upon the mold will be the consequence. l

The distance of the descent of the follower may be shortened, and the consequent pressure upon the molds .lessened by moving-the bar A back, as indicated by the dotted lines d,by means of the adjusting-lever C', the lowerV end of which is 'held in place,

by a pin droppingr into the holes F.

This backward adjustment of the bar allows the radial arms to slip from their engagement with thev lever sooner, as the distance it 'may-have to traverse scent of the follower and its pressure will becorrespondingly less.

The ascent of the follower is actuated in a corresponding manner and time by the shoulder D of the bar, hence, its descent and ascent is made -in 'equal time, as the adjustment of the rod may determine.

In connection with the table W, referred to, is used vportable t-able E', fig. 5, mounted upon the wheels As fast as the filled molds -are pushed out yfrom lVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The wheel I, provided with pivoted radial arms L M, more or less in number', substantially in vthe manner as described and for the purpose set` forth.

2. The levers F G, as arranged, in combination with the' standard E, when operated by the radial arms L M, iu the manner as described andl forthe purpose specified. v

3. The adjusting sliding bar A', as arranged in re-v lation to and in combination with the radial arms L M, substantially as and' for the purpose set forth.

4. The dischargngwheel N, provided with pivoted radial arms L' M', as arranged in relation to the wheel I and radial arms L M, and in combination with lthe arms P for operating the slide Q, in the manner sub stantially as described and for the purpose specified.
